This slow cooker recipe is the definition of set-and-forget comfort food. Flank steak, green beans, and potatoes cook low and slow in a velvety sauce made from cream cheese and Gruyère. Just layer everything in the Crockpot, cover, and walk away.
Hours later, you'll have a bubbling, fragrant dinner that tastes like you fussed — but you didn't. Serve it over toasted garlic brioche to soak up every last drop of the creamy, savory gravy.
There are slow cooker recipes, and then there are slow cooker revelations. This one turns a handful of everyday ingredients into a restaurant-worthy meal that feels both indulgent and effortless.
The flank steak becomes meltingly tender, the green beans stay slightly crisp, and the potatoes soak up all that cheesy goodness.
The sauce — a simple combination of cream cheese and Gruyère — transforms into a rich, glossy gravy that coats everything in pure comfort. It's the kind of dinner that makes a busy weeknight feel special.
Ingredients
- 2 lb flank steak, thinly sliced against the grain
- 1 lb fresh green beans, trimmed
- 1 1/2 lb russet potatoes, cubed (about 3 medium)
- 8 oz cream cheese, softened
- 2 cups shredded Gruyère cheese
- 1 tsp kosher salt
- 1/2 tsp black pepper
- Toasted garlic brioche slices, for serving
Why this recipe works
The slow cooker works magic on flank steak. This cut is naturally lean and can be tough if cooked quickly, but low, moist heat breaks down the connective tissue, turning it fork-tender. Slicing the steak thinly against the grain before cooking helps it stay tender and easy to eat.
The combination of cream cheese and Gruyère creates a sauce that is creamy without being heavy. Cream cheese melts into a silky base, while Gruyère adds nutty, savory depth. As the cheese melts and mingles with the beef's juices, it forms a rich gravy that clings to every ingredient.
Notes and substitutions
Choose a flank steak that is evenly thick for consistent cooking. If you can't find flank steak, sirloin or chuck roast work well — just slice them thinly.
Green beans should be fresh and trimmed; frozen can be used but may be softer. Russet potatoes hold their shape during long cooking, but Yukon Golds are also excellent.
Gruyère is the star of the sauce — its nutty flavor is irreplaceable. If you need a substitute, Swiss cheese or sharp white cheddar will work. For a truly authentic touch, use a 7-quart slow cooker; a smaller one may crowd the ingredients. The brioche is optional but highly recommended for soaking up the sauce.
